abc aja yah pake cara ya kak
[tex]1a. \: \: 1 \times 1 \frac{1}{3} = \frac{1}{1} \times \frac{4}{3} = \frac{4}{3} = 1 \frac{1}{3} [/tex]
[tex]1b. \: \: 5 \times 2 \frac{3}{4} = \frac{5}{1} \times \frac{11}{4} = \frac{55}{4} = 13 \frac{3}{4} [/tex]
[tex]1c. \: \: 4 \times 3 \frac{1}{6} = \frac{4}{1} \times \frac{19}{6} = \frac{38}{3} = 12 \frac{2}{3} [/tex]
[tex]2a. \: \: 2 \frac{1}{2} \times 4 \frac{2}{5} = \frac{5}{2} \times \frac{22}{5} = 11[/tex]
[tex]2b. \: \: 3 \frac{3}{4} \times 3 \frac{3}{8} = \frac{15}{4} \times \frac{27}{8} = \frac{405}{32} = 12 \frac{21}{32} [/tex]
[tex]2c. \: \: 2 \frac{4}{5} \times 4 \frac{1}{4} = \frac{14}{5} \times \frac{17}{4} = \frac{119}{10} = 11 \frac{9}{10} [/tex]
Semoga membantu

Penjelasan dengan langkah-langkah:
1.)
a. 1 × 1 1/3 = 1 × 4/3 = 4/3 = 1 1/3
b. 5 × 2 3/4 = 5 × 11/4 = 55/4 = 13 3/4
c. 4 × 3 1/6 = 4 × 19/6 = 76/6 = 12 2/3
2.)
a. 2 1/2 × 4 2/5 = 5/2 × 22/5 = 110/10 = 11
b. 3 3/4 × 3 3/8 = 15/4 × 27/8 = 405/32 = 12 21/32
c. 2 4/5 × 4 1/4 = 14/5 × 17/4 = 238/20 = 11 9/10
